Refactor og:description
to limit the max length (#26876)
1. The `og:description` should be "a one to two sentence description of your object" * It shouldn't output all the user inputted content -- it would be pretty huge. * Maybe it only needs at most 300 bytes. 2. Do not render commit message as HTML
